(Cl. 57-98) The present invention relates to an apparatus for controlling the building up of a cop on speed frames. More specifically, the present invention concerns a control mechanism for speed frames by means of which the contour of a predetermined cop or bobbin shape is in the form of a control program conveyed to a reversing gear transmission for reversing the direction of movement of the balling carriage and the infinitely variable transmission for changing the speed of the bobbins and for chang ing the speed of the balling carriage.

These control operations, have with heretofore known speed frames, been carried out by the so-called switch. This switch primarily comprises a rotatably journalled rocker which by means of the upwardly and downwardly moved balling carriage is subjected to an alternate weight load. The pawls which arrest said rocker in its respective end positions are lifted out by means of adjustable abutments arranged at another rocker moved by said carriage by linkage means. In this way, the rocker is released, tilted, and thereby reverses the reversing transmission through the intervention of linkage means.

Simultaneously with the actuation of said rocker, two pawls are shifted over which thereby permit an index gear which is under the load of a weight to turn by half a tooth pitch. This index gear will then, in view of its turning movement through a suitable transmission, displace the cone belt bar and the link system actuating the rocker.

The form of the bobbin winding or of the cop and, more specifically, the height and the conical angle thereof are determined by the adjustment of the abutments of the rocker actuated by the balling carriage, and furthermore by the teeth of the indexing wheel and the length of the link member at the start and the end of the withdrawal operation. The adjustable abutments on the rocker actuated by the balling carriage determine the level of the winding.

The mutual influence and interdependence of these adjusting elements make it rather difiicult to obtain a certain desired bobbin shape, and for all practical purposes, this is possible only by a rather time-consuming trial-and-error method.

It is, therefore, an object of the present invention to provide a simple and more positive method which will overcome the above-mentioned drawbacks.

It is another object of the present invention to provide an apparatus of the type involved which will make it possible to cause the speed frame truly to reproduce a desired bobbin shape in conformity with a predetermined geometrical contour.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:

FIGURE 13 shows an arrangement similar to that of FIGURE 12 but with circularly curved, rigid rulers;

FIGURE 14 shows an arrangement similar to that of FIGURE 13 but with variable curvature.

The problem underlying the present invention has been solved by reversing the lifting movement which brings about the building up of the bobbin, in conformity with a template which is geometrically similar to the generatrix of the winding trapezoid of the bobbin, said template having two legs which are scanned by feelers gradually displaced in a direction transverse to their feeling direction.

In order to realize the method according to the present invention, it is suggested, in conformity with the present invention, on a switching apparatus with sta tionary switching elements which by reversing a reversing transmission reverse the lifting movement of the winding-up station and by actuating a stepping mechanism, through a control to adjust the infinitely variable transmission in the drive of the bobbin and the lifting movement. Furthermore, the invention provides a feeler which is moved back and forth synchronously with the lifting movement of the winding-up station of the rover, and by a stepping mechanism is, within the course of the withdrawal gradually displaced in a direction perpendicular to said first-mentioned direction of movement. According to the invention, there is furthermore provided a carriage with two rulers which are engaged by the feeler whereby the carriage is displaced until one of its control cams actuates one of the two switching elemerits which reverse the reversing transmission.

According to another embodiment of the invention, the switching apparatus has a template with two rulers which are, synchronously with the lifting movement of the winding-up station of the roving, moved back and forth and in the course of a withdrawal are gradually displaced in a direction perpendicular to said first-mentioned direction of movement. There is also provided a carriage with one or two feelers engaged by the rulers whereby the carriage is displaced until one of its control cams actuates one of the shifting elements which reverse the reversing transmission. Each shifting element may have associated therewith a carriage.

The adjustment of the winding level is in conformity with the present invention to be effected either by ad justing the distance of the rulers in the carriage in the direction of movement of the carriage by adjusting the.

J one of the variable transmissions which may be inserted in the power train for conveying the lifting movement from the winding-up station to the feeler, and by displacing the switching elements in the direction of movement of the carriage.

The adjustment of the opening angle of the winding cone may be effected by adjusting the inclination of the rulers with regard to the direction of movement of the carriage or by varying a variable transmission which is inserted in the power train for conveying the stepping movement from the control shaft to the feeler.

In order to increase the lifting strokes of the abutment and of the carriage, or advantageously to reduce the same, it is possible to interpose a variable lift step-up or stepdown transmission into the power train for conveying the lifting movement from the winding-up station to the feeler.

According to a preferred realization of the invention, the feeler is designed in the form of a roller. However, it may also be designed in the form of two feelers which are adjustable relative to each other in the direction of movement of the carriage.

Finally, the carriage may carry a plurality of adjustable control cams each having associated therewith a switching or shifting element.

Referring now to the drawings in detail, FIG. I illustrates the normal shape of a roving bobbin of a speed frame the winding body 1 of which is built up in the customary manner, i.e. in the form of a so-called parallel winding. The winding body of the bobbin may be viewed as a trapezoid of rotation, in other words, as a body which has been generated by rotating an isosceles trapezoid 2 about the bobbin axis 3 (FIG. 2). This isosceles trape zoid 2 represents a template which is determined by the distance between and the inclination of its legs 4 and 5 and the height and opening angle of the winding body to be built up. The final diameter of the bobbin is determined by the length of the wound-up roving and by the number of the winding layers.

The principle of the invention consists in that a template of this type serves as control program for the actuation of the control transmission of the speed frame and is gradually scanned by feelers in the course of the withdrawal. By means of the thus created control impulses, those parts of the speed frame are controlled which determine the build-up of the winding. The scanning of the template may, in conformity with FIG. 3, be effected from the inside or, in conformity with FIG. 4, be effected from the outside while template and feeler are moved relative to each other in two directions rm and bb. In this connection, aa always represents a reciprocatory movement, whereas bb indicates a stepping movement in one direction only. The sense of direction, however, depends on whether the feeler or the template is being moved.

The operation of an arrangement according to the present invention will now be described in connection with FIG. 5 and pertaining to a speed frame of the customary construction. It is, however, to be understood that the present invention is, by no means, limited to speed frames of this type.

Referring now to FIG. 5, the main motor 6 through a pair of bevel gears 7 drives the spindle 9 carrying the fiyer 8 and also drives the drafting mechanism of the speed frame (not illustrated). By means of an infinitely variable transmission 10 and bevel gears 11, the bobbin pinions 13 meshing with gears 11 and carrying the bobbins 12 will be driven. In order to simplify the illustration, FIG. 5 shows only one of a plurality of spindles of the speed frame. The bobbin pinions 13 are rotatably journalled in the balling carriage or bobbin rail 14, which is vertically movable and is driven through the intervention of a pinion 15 and gear rack 16 by an infinitely variable transmission 10 and an interposed reversing transmission 17.

A feeler 18 is, for instance by means of a coulisse system arranged on bobbin rail 14 in such a way that it takes part in the lifting movement an of the bobbin rail but is displaceable bb transversely to the direction of movement of the bobbin rail. This displacement is effected, for instance, through the intervention of a threaded member 20 which is guided on a control shaft 19 designed as a threaded spindle and in which the feeler 18 is, in its turn, guided for instance, by means of a second coulisse system. The auxiliary lines 21 and 22 indicate the central lines of the two coulisse systems which coulisse systems are perpendicular to each other and guide the feeler 18. These coulisse systems connect the feeler 18 with the bobbin rail 14 and also with the control shaft 19. During the upward and downward movement of the bobbin rail 14, the feeler 18 alternately abuts one of the two legs 23, 24 of the carriage 26 which is slidably guided on guiding means 25. Carriage 26 is displaceable to such an extent that it is able by means of its control cams 27 and 28 to actuate the two switches 29 and 30. The feeding line to switches 29, 36 is designated with the reference numeral 31. Through lines 32 and 33, the control impulses of switches 29, 30 are conveyed to the reversing transmission 17 and to a stepping mechanism 34- which rotates the control shaft 19 and thereby adjusts the infinitely variable transmission 16 and the feeler 18. Line 31a is the other side of the electric power supply of which line 31 is a part. A spring 35 balances the weight of th carriage 26.

The operation of the device is as follows: When the bobbin rail 14 moves downwardly, also feeler 18 is moved downwardly. During this downward movement feeler 18 hits leg 24 of carriage 26 and moves the latter downwardly until carriage 26, by means of its control cam 28 hits switch 30. As a result thereof, switch 30 closes a contact and through line 32, an impulse is conveyed to the reversing transmission 17 which in this way is reversed and reverses the direction of movement of the bobbin rail 14. The same impulse also actuates the stepping mechanism 314 which, consequently turns the control shaft 19 by an adjustable angle and adjusts the infinitely variable transmission 10 as well as displaces the feeler 18 in a direction transverse to its lifting movement with the bobbin rail. More specifically, this displacement corresponds to the increase in diameter for the new winding layer.

During the upward movement, the just-described cycle is repeated with the only difference that the reversing transmission 17 is again moved into its other end position, whereas the stepping mechanism 34 is advanced by one step. In this connection, feeler 13 is adjusted in the direction of the decreasing distance of legs 23 and 24 of the carriage, so that at the next stroke it will hit the respective leg somewhat earlier whereby the control impulse by carriage 26 is released at an earlier stage and the lifting height of the bobbin rail 14 is reduced correspondingly.

Various designs are possible for the template and the feeler, FIGS. 6 to 9 illustrating one of these possible embodiments.

FIG. 6 corresponds to the arrangement of FIG. 5. The reciprocatory movement of feeler 18 in the direction an is effected synchronously with the movement of the bobbin rail, b indicating the direction of the stepwise advance of feeler 18.

According to the embodiment of FIG. 7, the carriage is divided into two independent carriages 35 and 36, of which one carriage actuates switch 29 by means of control cam 27, whereas the other carriage actuates switch 30 by means of control cam 28. As has been illustrated diagrammatically in FIGS. 8 and 9, it is also possible to move the template 2 and to arrange the feelers 18 and 18' on carriage 26. The movement of template 2 is effected in the same manner in the direction aa and b as described above in connection with feeler 18.

Whereas according to FIG. 8, the moved template is scanned from the outside, according to FIG. 9 the scanning is effected from the inside. In the following figures, b indicates the direction of the stepwise advance.

FIGS. and 11 illustrate an embodiment. of the invention in greater detail. The reference numeral 37 designates the shaft, rotation of which causes the described movement of the bobbin rail. Shaft 37 may be designated lifting shaft. The lifting movement of the bobbin rail is, through the pair of bevel gears 38, the gear transmission 39 which is preferably equipped with a variable step-up and StCPrdOWIT transmission, and pinion 40, conveyed to gear rack 41"which latter is mounted on a supporting member 43 which is displaceable on a guiding bar 42. Guided in supporting member 43 is a slide 44, and a roller 45 is rotatablyjournalled on said slide 44. Slide 44 is displaceab'le transversely to the direction of movement of the supporting member 43 and is provided with teeth 46 meshing with a pinion 47. Pinion 47 is rotatably journalled in "supporting member 43 and is axially displaceable on a shaft 48 but rotatably connected thereto by means of a key 49 and groove. The reference numeral 19 designates a control shaft the rotative movement of which is by means of'a pair of bevel gears 50, if desired, by a step-up or step-down transmission 51 conveyed to shaft 48. r

In contrast to the automatically moved parts, viz. supporting member 43 and slide 44 with roller 45, slide 52 is freely displaceable on the guiding bars 53 and 54. At both wings of slide 52, there is arranged rulers 55 and 56 each of which is tiltable about a bolt 57 and by means of a clamping screw 58 is adjustable in slide 59. The inclination of rulers 55 and 56, which in this way is variable, may be read at the scales 60 and 61. Instead of the illustrated straight rulers which will produce straight winding cones, it is also possible, as control edges of the template, to employ curved rulers which will,for instance, form convex winding cones.

Slide 52 carries two control earns 27 and 28 which, during a displacement of the slide will actiiate switches 29 and 30. If it appears advantageous to carry out the two control steps, viz. the reversing of the rey'ersing transmission 17 and the advancing of the control shaft 19 not at the same time but at a slightly adjustable time interval, each of the two sides of slide 52 maybe equipped with two control cams 27, 66 and 28, 67, which are independently adjustable on the slide in the iiirection of movement an of the slide. For effecting said adjustment, each cam has a slot extending in the direction of adjustment thereof anda clamp screw extending through the slot and threaded into the slide. These adjilstable control cams each are adapted to act upon separate control elements 29, 29a at one side, and 30, a at the other side. Springs 62 and 63 always return slide 52 to its intermediate position.

During the upward movement of the bobbin rail by means of the lifter shaft 37, through the intervention of transmission 39, pinion 40 and gear rack '41, also the supporting member 43 and together with the latter slide 44 and roller 45 are moved, for instance, toward the left. During this movement, the feeler roller 45 abuts the ruler 55 and thereby takes along slide 52 until the latter, by means of its control cam 27 actuates switch 29. As a result thereof, in the manner described above, the direction of movement of the bobbin rail is reversed, and control shaft 19 is rotated by one step, while through the intervention of pinions 50 and 51 and shaft 48, slide 44, and with the latter, roller 45 are displaced somewhat further upwardly so that during the next stroke, roller 45 will hit the ruler 55 earlier whereby slide 52 is carried along earlier and switch 29 is actuated earlier with the result that the stroke of the bobbin rail will be reduced. The same operation willoccur at the lower reversing point of the lifting movementand will bebrought about by means of the parts arranged on the other half of slide 52.

After the withdrawal has been completed, control shaft 19 and the stepless transmission 10 and feeler roller 45 are returned to their starting positions. The adjustment of the desired bobbin shape with regard to the winding cone may, as mentioned before, be effected by adjusting the inclination of the rulers 55 and 56. A further possibility consists in changing the transmission ratio of movement between the bobbin rail and the feeler on transmission 39. This engagement also affects the height of the winding bobbin, which may be corrected by other steps.

With regard to the winding height, the bobbin shape may, in addition to the already mentioned change in the transmission ratio of the movement between bobbin rail and feeler roller, be changed also by changing the distance of the rulers 55 and 56 with regard to each other. This may be effected in a simple manner in conformity with the illustration of FIG. 12 by an adjustable arrangement of rulers 55' and 56' in the feeling direction. The rulers 55 and 56 are adjustable in the oblong holes 52a, 52b of slide 52 and are rotatable about bolts 57a and 57b. The said bolts, when tightened, clamp the rulers in any adjusted position.

The same effect may also be obtained as indicated diagrammatically in FIG. 7 by providing two feeler rollers 64 and 65 the distance apart of which is adjustable. A greater distance between rollers 64 and 65 corresponds to a lower height of the winding. A similar arrangement consists in selecting the starting position of roller 45 in direction I) in such a way that in this starting position, the lifting height of the bobbin rail corresponds to the desired winding height. Finally, it is also possible to adjust switches 29 and 30 in conformity with the desired winding height. The rollers 64 and 65 could be adapted to the system of FIG. 5 by replacing roller 18 by the two rollers 64 and 65 with each thereof having its own support member, the two support members being adjustably connected together and being connected as a unit to the support for roller 18.

FIG. 13 illustrates an arrangement in which circularly curved rigid rulers 55 and 56" are provided. These rulers are each provided with an eye 55a and 56a by means of which through the'intervention of clamping screws, the rulers can be clamped in oblong holes 52a and 52'b in slide 52, while it is possible to vary their distance apart as well as their inclination.

FIG. 14 illustrates rulers 55 and 56' which are adjustable as to their curvature. These rulers consist of flexible band-shaped bodies of metal or synthetic material which protrude from the drawing plane and which are provided with angled-off members 55c, 560. At these members, which are expediently provided with oblong holes 55d, 56d, said rulers are likewise arrestable by means of screws 55e, 56c in oblong holes 55], 56 in slide 52. In the particular illustration of FIG. 14, said rulers follow the shape of a parabulum or hyperbulum.

In view of the exchangeability of the rulers, which are simple and inexpensive, a device according to the present invention excels by its great flexibility with regard to the shape of the cone flanks. This advantage is par ticularly great when the rulers are flexible.

It is, of course, to be understood that the present invention is, by no means, limited to the particular constructions shown in the drawings, but also comprises any modifications within the scope of the appended claims.
